Kia Ora Misato,
For years we have been conditioned to think in a certain way, which conjures up emotions to go with the particular thought, and they[thoughts and emotions] have developed a habit of feeding off each other-hence the continuous cycle, and the rut that many people seem to get into and find hard to get out of ...
We live with our thoughts and through our thoughts, ie, "What we 'think', we are/become !"
There's a famous Tibetan Buddhist mantra [well I think the words are actually in the Pali language] "Om Mani Padma Hun !"
When roughly translated means "The Jewel is in the Lotus !" And in plain English "What one seeks one already is !" Or "What we seek we are !"
However with time and effort one can change ones 'thought' pattern creating more 'wholesome' habits and emotions...
"If you correct your mind, the rest of your life will fall into place !"Metta Zenda
